GaAs HBT PRE-DRIVER AMPLIFIER
GaAs HBT Pre-Driver for Basestation Amplifiers
Power Amplifier Stage for Commercial Wireless
Infrastructure
Class AB Operation for GSM/EDGE/
CDMA2000/W-CDMA Transmitter Applications
The RF3805 is specifically designed for wireless infra-
structure applications. Using a highly reliable GaAs HBT
fabrication process, this high-performance dual-stage
amplifier achieves high output power over a broad fre-
quency range. The RF3805 amplifier also provides excel-
lent efficiency and thermal stability through the use of a
thermally-enhanced surface-mount AlN package. Ease of
integration is accomplished through the incorporation of
an optimized evaluation board design provided to achieve
proper 50
operation. Various evaluation board configu-
rations are available to address a broad range of wireless
infrastructure applications:
GSM/EDGE1800
CDMA2000
W-CDMA
5W Output Power
High Linearity
40% Power-Added Efficiency
